SU112642A1 - Liquid Flow Regulator - Google Patents

Description

Odor liquid is added to the gas to impart odor to domestic gas transported over a long distance gas pipeline, such as Sar.atov-Moscow. Usually, the supply of this liquid to the gas was taken manually. The main disadvantage of this adjustment is that during fluctuations in gas flow, for which the operator does not have time to monitor, the odorant supply remains constant for a certain period of time and therefore the gas is excessively enriched or depleted when the flow rate decreases.

The proposed device automatically dispenses the odorant, depending on the amount of gas flowing through the pipeline. The instrument uses an okraobr: compensator, which serves to reconfigure the instrument to different limits of measuring the amount of flowing gas.

The drawing shows the described controller.

The device is made on the basis of a differential manometer and consists of two communicating vessels 1 t 2 filled with mercury. An annular float 3 is placed in one of the vessels, on which stands 4 of steel wire are fixed. Using the legs, the float is connected to the blade-like compensator 5 and to the vertical axis 6, one end of which is connected to the cylinder 7 having calibrated orifices, and the other end is led out into a glass tube 8 to indicate the position of the float. The cylinder 7 is connected by means of a spiral tube 9 to the float chamber 10, into which a float 11 is placed, which serves to close the inlet with a needle valve 12, in case of overfilling the chamber with an odor.

When the gas flow rate in the pipeline changes, the pressure in the impulse tubes 13 changes, and this causes the position of the float 3 to change. Moving the float through the racks 4 is transmitted to patternN "112642-2 -

the figurative compensator 5 and the cylinder 7, as a result of which the height of the column of odorant in the cylinder, as well as the number of odorant droplets flowing through the bottom calibrated opening in the gas pipeline,

The KoiviHCHcaTop consists of a control paw 14, on the upper side of which there is a slide for sliding, restricting the rotation of the shift pad. The washer is equipped with guiding patterns 15, which are moved apart by the action of a load or tons of 16. There are holes for fastening fasteners on the plane of the washer. Shifting from one hole to another, you can rotate the washer by 90 ° and thereby reconfigure the instrument to other limits for measuring the amount of flowing gas. The use of a laser-compensated compensator that takes into account the quadratic z.dependence of the pressure drop on the gas flow rate makes it possible to ensure that the quantity of one odor is equal to the amount of gas.
